2. Check if the correct water inlet valves are
Functional.
If the cold water inlet valves are not
functional or if the main cold water supply is
not available and only hot water inlet valves
are open, and if the hot water supply has a
temperature value above the programmed
wash sequence value then the temperature
of the wash bath will be too high.
3. Check the water temperature.
4. Check if the temperature sensor is
functioning.
5. Check if the heating contactor stays closed.
(check voltage to contactor coil.)
6. Check the output relay that powers the
heating contactor.
7. Check the output relay that powers the
heating contactor.
FAILURE 21: OVERFLOW FAILURE
When the water level is raising above the hole of the overflow tube: message 21 will be displayed.
DIAGNOSE:
1. Check if the overflow hole and tube isn't
blocked.
2. Check if the drain tube isn't blocked.
3. Check the water inlet valves.
4. Check the output relay that powers the
water inlet valve.
FAILURE 24: DEFECTIVE LEVEL SENSOR
If the level sensor is broken then fault 24 will be displayed. The fault is only generated when the machine is in
standby mode and no wash cycle is running.
The fault can only be erased by switching off and on the power.
DIAGNOSE:
1. Check the level sensor visually.
2. If the fault is persistent.

See diagnostics Failure 11 : Fill Failure
If the temperature of the supplied hot water is too high:
decrease the temperature of the hot water.
If the temperature sensor is defective:
replace the temperature sensor.
If the heating contactor stays closed : Replace the
heating contactor.
If the relay stays closed and the relay is broken,
replace the power board.
If the relay is not broken, but receives a not allowed
signal from the wash computer, replace the wash
computer.
If the overflow tube is blocked: repair the tube.
If the drain tube is blocked: repair the drain tube.
If the water inlet valves are broken: replace the water
inlet valves.
If the relay stays closed and the relay is broken,
replace the wash computer.
If you see some damage: replace the wash computer.
Replace the wash computer. (be sure there is no drain problem)
